This extension nozzle comprises a tubular conduit 40 preferably of sheet metal, although not necessarily, which is securely fastened as at 42 within mg end walls a of curved .cdntour. The front, the base of the tubular nozzle 28. The bottom back and side walls are preferably formed of a end nozzl? 15 open and 15 preferably fqrmed single plate of metal seamed together at one of on a diagonal blas as at 44 whereby perFmt the thecurved sides as is Well known in the art powdered contents of the can to flow easily into T container is provided with a top w and a the funnel-like mouth of the nozzle or tubular 45 bottom l2, both of which are seamed to the main condult body f the container in 11 known manner Instead of spotwelding, soldering or otherwise as shown at, Hand iii in Figures 4 and 5. Either affixing the nozzle 49 as at 45 to the the front or back of the container is provided with a W l 8, I prefer to affix it in position in the 50 a collapsible bellows type of device for forcibly manner Set forth in Figure wherein the exteh- 50 expelling the powdered contents of the can. S1011 nozzle 49 provided with a Preferably The invention herein is not in the specific form uate extension or tip 48 which is placed in posiof collapsible bellows construction except as to tion in registration with the lower end of the can the manner in which the same enters into comwall 8 so that in the seaming operation the botbination with the can and the nozzle construc- 13 m 12. is carried over both the side 8 and the 66 extension 48 to form the seam and likewise to hold the bottom of the nozzle in position.

It will be understood that my invention is not limited to the cross-sectional dimensions of the can nor to the shape of the can, but is adapted to any general shape of container and may take other forms, provided they are embraced within the scope of the appended claims. It is also obvious that the container may be made of paper or other suitable material.

When the can is upright the powder at the bottom will always tend to flow into the funnelshaped bottom 44 of the sleeve 40, thus filling the extension nozzle 40 so that a direct charge of this powder is always in position to be p ojected by the air in the can compressed by the bellows mechanism. Therefore, irrespective of the position of the can, powder will always be fed to the outside nozzle.

Having thus described my invention what I claim as new and desire to be secured by Letters Patent is as follows:

1. A shipping and dispensing container for powdered material, comprising a tubular body wall having opposed substantially fiat end closures secured thereto, one of said closures having an opening closed by a removable cap for filling and refilling said container, a powder dispensing nozzle carried in one of said end closures, means for sealing said nozzle to prevent deterioration of the container contents and accidental dispensing of the same, said body wall having a cutout portion defined by an annular bead and a clamping ring, and a bellows member disposed within said container for ejecting said contents through said nozzle when said sealing means is removed, said bellows member including a flexible diaphragm having its marginal portion secured between said annular bead and said clamping ring.

2. A dispensing container having side walls and a collapsible bellows formed in one of said walls, said container having a nozzle through which powdered contents within the container are adapted to be expelled upon the operation of the bellows, said nozzle having a tubular extension projecting from a point adjacent the bottom of the container directly to the nozzle and open to the interior contents of the container, said nozzle being of substantially funnel-shaped dimensions, said nozzle also having its lower end cut on a diagonal line to facilitate the entry of the powdered contents into the nozzle.
